LoCoMoTlvE ASH-PAN.

SPECIFICATION forming part of Letters Patent No. 286,579, dated October 16, 1883. Application inea June 4, 1883. (No man.)

To all whom t may concern:

Be it known that I, EDWARD BIGNELL, a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in Locomotive Ash-Pans, of which the following is a (specification, reference being had thereinto the accompanying drawings, in which- Figure lis a side elevation, partlyinv section, of a locomotive provided with my improved ash-pan. Fig. 2 is a longitudinal and Fig. 3 a, transverse section of the ashpan.

Like letters refer to like parts in all the iigures.

The object of my invention is to'provide means for preventing the adhesion of snow and ice to and uponvthe ash-pan of locomotive-boilers; and I attain this object by constructing the ash-pan so as to adapt it to be heated by causing steam, either'live or exhaust, to be directed against the walls of the same. It is well known that the ash-pans of locomotives are located at a comparatively low point, and near the ground, and that in passing over the road-bed in snow of even ordinary depth a quantity is scooped up by, or is almost constantly in contact with, the ash-pan, and by reason of the heat therein the snow becomes melted, and subsequently freezes, so that' at times the door of the pan becomes clogged and difficult to open.

the space or spaces between said walls andwith the boiler or other suitable part of a locomotive where steam, either live or exi haust, may be supplied and 'conducted by said pipes. Various arrangementsof these elements may be employed, and may be suggested by ordinary mechanical skill. I therefore do not limit myself to the exact arrangement herein shown, but reserve the right to modify the same as circumstances may indicate to be preferable.

In this instance I arrange a supplypipe,

Br` Amy construction steam is directed against the pan, so as to maintain such a temperatureV thereof as to melt any snow which may be- -A, extending from the steam-chamber of the desired point in this supply-pipe, also, if de-` sired. In these particular arrangements of pipes changes may be made, as above stated; but I prefer facilities of some sort for supplying both live and exhaust steam at will, though either alone will accomplish the primary object in view.

E represents the ash-pan, and it comprises7 in addition to the usual features of construction, a duplicate bottom plate, e, and Walls e', which are bound together by space-bars e2, angle-irons e3 at a corner or corners, and tiebolts or rivets e", in such a manner as to form a space or spaces between the inner and outer walls, through which spaces the steam entering by either of the supply-pipes A -or C passes; and I provide one or more holes, e5, in the' outer bottom plate, e7, for the escape or discharge of the steam and any water of condensation therefrom.

The operation is apparent from the foregoing description, and it is evident that snow cannot accumulate or ice form upon Vany parts of the walls or bottom of the ash-pan, and usual obstructions to draft or grate surface can be easily removed and prevented from obstructing the free operation of vconnectingrods to gratos, the grates, and doors E.

Having described my invention and its operation, what I claim is- The combination of an ash-pan provided 'with duplicate bottom plates, and a steampipe communicating with the exhaust and with the space between said plates, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD BIGNELL.
